Just need to rant I guess?

I’ll preface this by saying I haven’t been diagnosed with depression. But it sure does feel like I have some form of it. I don’t know if that’s a requirement for this section but I really didn’t know where else to post this so sorry if it’s in the wrong section haha. Ever since I started college I can’t seem to be happy about anything anymore. In august I started at a college I had initially fallen in love with. I actually made a thread before about how lonely I was there early on... it didn’t get much better from there. About 3 weeks in I realized how miserable I was there. I didn’t have any friends going there with me and covid made it 100x harder to meet people. There were some school things that upset me too, but most of my problems with that school had to do with loneliness. I talked to my parents about transferring and I did! I visited the campus of my new school and loved it, and this school has a really good music program (I’m majoring in music education). The first couple of weeks here were great. I have friends here that introduced me to other people, I’ve found an apartment for next year, and I’m doing well in my classes so far. Everything seems like it should be going fine but I just can’t seem to get happy and I don’t know what’s wrong with me. I still feel lonely a lot of the time, even though I have friends here. I also have a really busy schedule and am now taking private piano lessons with a professor that makes me feel like I don’t know anything even though I’ve been playing piano for 10 years. My voice teacher is also about 80 years old so I’m forced to do zoom voice lessons, which I know aren’t giving me everything I need to be a successful vocalist. On top of all of this, my friend is going through a really rough time with his parents and I’m scared for him. Finally, I made a mistake one night and now there’s a chance I could be pregnant... a very very VERY tiny chance, but I can’t get my mind off of it. I have no idea what to do. I know I’m letting all this stuff pile up on me and make me feel worse about it all but I don’t know how to let it all go. I’m just tired.
